I am loving this thread!
This might be a little outlandish but.... does the bible have any mention of dinosaurs or aliens? Some people like to say that this is in there but I have never seen it (although I haven't read the bible entirely either).
Thank you delitefulmane; it's a great place to ask and share those questions and answers that we've thought about, but never had a chance to ask.
Each and everyone of us has a wealth of information to share with each other. It's a good thing to share, our hearts and knowledge.
As for dinosaurs and aliens.
The Bible speaks of beasts in several places, however the ones that come to mind are in Job chapter 40 and 41 and in Isaiah 27. In Job chapter 41 and Isaiah 27 it speaks of a sea 'beast' who was large and dangerous and was called a Leviathan. In Job chapter 40, the Bible mentions the Behemoth which was a huge beast upon land.
Here's some of the scriptures:
Job 40:15-24
15Behold now behemoth, which I made with thee; he eateth grass as an ox.
16Lo now, his strength is in his loins, and his force is in the navel of his belly.
17He moveth his tail like a cedar: the sinews of his stones are wrapped together.
18His bones are as strong pieces of brass; his bones are like bars of iron.
19He is the chief of the ways of God: he that made him can make his sword to approach unto him.
20Surely the mountains bring him forth food, where all the beasts of the field play.
21He lieth under the shady trees, in the covert of the reed, and fens.
22 The shady trees cover him with their shadow; the willows of the brook compass him about.
23
Behold, he drinketh up a river, and hasteth not: he trusteth that he can draw up Jordan into his mouth.
24He taketh it with his eyes: his nose pierceth through snares.

Oh wow... check out this "sea monster", he' pretty tough
Job 41:1-
1Canst thou draw out leviathan with an hook? or his tongue with a cord which thou lettest down?
2Canst thou put an hook into his nose? or bore his jaw through with a thorn?
3Will he make many supplications unto thee? will he speak soft words unto thee?
4Will he make a covenant with thee? wilt thou take him for a servant for ever?
5Wilt thou play with him as with a bird? or wilt thou bind him for thy maidens?
6Shall the companions make a banquet of him? shall they part him among the merchants?
7Canst thou fill his skin with barbed irons? or his head with fish
8Lay thine hand upon him, remember the battle, do no more.
9Behold, the hope of him is in vain: shall not one be cast down even at the sight of him?
10None is so fierce that dare stir him up: who then is able to stand before me?
11Who hath prevented me, that I should repay him? whatsoever is under the whole heaven is mine.
12I will not conceal his parts, nor his power, nor his comely proportion.
13Who can discover the face of his garment? or who can come to him with his double bridle?
14Who can open the doors of his face? his teeth are terrible
15His scales are his pride, shut up together as with a close seal.
16One is so near to another, that no air can come between them.
17They are joined one to another, they stick together, that they cannot be sundered.
18By his neesings a light doth shine, and his eyes are like the eyelids of the morning.
19Out of his mouth go burning lamps, and sparks of fire leap out.
20Out of his nostrils goeth smoke, as out of a seething pot or caldron.
21His breath kindleth coals, and a flame goeth out of his mouth.
22In his neck remaineth strength, and sorrow is turned into joy before him.
23The flakes of his flesh are joined together: they are firm in themselves; they cannot be moved.
24His heart is as firm as a stone; yea, as hard as a piece of the nether millstone.
25When he raiseth up himself, the mighty are afraid: by reason of breakings they purify themselves.
26The sword of him that layeth at him cannot hold: the spear, the dart, nor the habergeon.
27He esteemeth iron as straw, and brass as rotten wood.
28The arrow cannot make him flee: slingstones are turned with
29Darts are counted as stubble: he laugheth at the shaking of a spear.
30Sharp stones are under him: he spreadeth sharp pointed things upon the mire.
31He maketh the deep to boil like a pot: he maketh the sea like a pot of ointment.
32He maketh a path to shine after him; one would think the deep to be hoary.
33Upon earth there is not his like, who is made without fear.

Isaiah 27:1
1.. In that day the LORD with his sore and great and strong sword shall punish leviathan the piercing serpent, even leviathan that crooked serpent; and he shall slay the dragon that is in the sea.
Special Note: I have wonderful testimony with Isaiah 27... God is so awesome. I'll have to share it with you one day.

Whew!
Is it believed by many that these were the beasts (prehistoric/post history).
Now as for aliens, no 
If one has seen an alien, then it was demon spirit. And to be honest, a demon
is an alien in this earth for without a human body, it is illegal to be in the earth realm.
When the Bible speaks of the word, 'alien' it means one who is/or was alienated from Jesus Christ (Ephesians 2). ... for God made the two 'One'. Because of the Blood of Jesus we are no longer alienated from Christ Jesus our Lord.
I know the other members can expound on this. I'm looking forward to their responses.
Healthy Hair, I didn't pay attention to that in my studies before, thanks for pointing this out. 
for now.
I've always loved Proverbs 31.
